Here's an idea I've been tossing around lately- Apple should make an Instagram clone for iCloud users.
Instagram is one of the last social networks I use these days, which I actually enjoy visiting. But I always get a little twitchy using it because it's owned by Facebook (which I'm really not a fan of). And the ads are getting pretty annoying these days.
So wouldn't it be awesome if Apple made a privacy focused clone of it? I know Apple doesn't really do well when it comes to social services, but I'm wondering if a simple photo sharing site might not be impossible for them to do well. From the outside, it looks like it's just a scaling problem. You've got photos, comments, and a list of folks to watch. It can't be that hard.
Start small. Make it clean and minimal. Add a developer API. Grow it slowly with beta invites. Why not? It's a pretty good fit if you ask me.
